AUTOMATIC WATERiNG-TROUGH.

SPECIFICATION forming part of Letters Patent No. 634,504, dated October 10, 1899.

Application ant June 19, 1899.

To all wl'uom it may concern:

Be it known that 1, CHARLES H. PRESBREY, a citizen of the United States, residing at Sterling, in the county of Whiteside and State of Illinois, have invented certain new and useful Improvements in Automatic VVatering- Troughs; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the ac-v companying drawings, and to the figures and letters of reference marked thereon, which form a part of this specification.

My invention relates to automatic wateringtroughs, the operation of my device being substantially like that of similar devices -now in use, the improvements thereof consisting, chiefly, of an elongation of the floatchamber, resulting in an increased leverage of the float; also, a consequent narrowing of the float-chamber,whereby the drinking-compartments may be brought closer together, necessitating'the use of considerablyless material in the manufacture of the troughs. The construction of the float-chamber in my device also insures a freedom of such chamber from the accumulation of impurities or sediment therein and a consequent free action of the float at all times. I also make use of a construction whereby the automatic portion of my device may be first attached to the main reservoir and the trough afterward secured thereto;

In the drawings, Figure 1 is a plan view of my device as in use. Fig. 2 is a similar view with the cover of the float-chamber removed. Fig. 3 is a cross-section in the line wacof Fig- 1. Fig. eiis aview of the float-chamber cover in perspective. 1

Similar figures and letters refer to similar parts throughout the several views.

1 is an ordinary watering-trough consist ing of two compartments 2 2.

3 is a short pipe adapted to be secured in the wall of a tank or other reservoir and projected outwardly into the valve-chamber 4, having an opening in its lower facein'which is operated the cone-shaped valve 5 upon the horizontal valve-seat 6. The valve 5 is.actuated by the lever 7, pivoted, as at a, and secured at its outer end to the hollow spherical overlap the edges of the channel 11.

float 8, having vertical playin the semicircw lar portion of the float-chamber 9, formed by the enlargement in the front Wall of the trough 1. Afterpassing through the pipe 3 and valve-chamber 4 the water fallsinto the shallow-channel 11 between the ridges 12. The channel 11 slopes and narrows outwardly, and the water runs down such channel and into the bowl of the circular portion of the float-chamber 9, from whence it passes into the compartments 2. The pipe 3 is provided with the square neck 13, adapted to set into andloe held by a corresponding recess in the rear wall of the trough 1, the removal of such pipe being prevented when the cover, hereinafter referred to, is in place.

V is a cover having concave sides 16,which When the cover is in place, the top and sides thereof inclose and complete the float-chamber. The cover 15 is further provided with the small dome 17,which is immediately above the float 8 when the cover is in position and permits the elevation of such float above the line of the upper edge of the trough 1. The cover 15 is secured to thetrongli 1 by means of the in its central part, between the drinking-compartments, which compartments are thus This construction of the floatchamber also permits of its being narrowed The elevated position of the valve mechanism tends to keep the same above any accumulation of sediment there might be in the trough, and'this condition is further insured by the downward tendency of the water after leaving the tank, aided by the sloping channel 11, the direction of the current being constantly throughthe bowl of the enlarged portion of the float-chamber and immediately beneath the float. The sediment comes from without, finding its Way first into the drinking-compartments, and in my device such compartments would have to be pretty Well filled before the sediment would work up into the float-chamber and would require cleaning.

In attaching my device to'the main tank the cover can be removed, the valve and float mechanism released'and secured to the tank, and the trough and cover again placed in position.

WVhat I claim as my invention, and desire to secure by Letters Patent of the United States, is-

1. In an automatic Watering-trough, the float-chamber 9, provided with the enlargement 10, in combination with automatic valve mechanism controlling the flow of water through such float-chamber; and the float 8, located in such enlarged portion 10, substantially as set forth.

2.- In an automatic watering-trough, the float-chamber 9, located so that the bottom thereof is about midway the bottom and top of such watering-trough; said float-chamber having the enlarged portion 10, and being further provided with the sloping channel 11, by which the current of water through such float-chamber is directed into the lower part of such enlargement 10; said float-chamber being adapted to contain automatic valve mechanism for controlling the flow of water therethrough; substantially as shown.

3. In a float-chamber for automatic watering-troughs, the combination of the channel 11, forming the bottom thereof; the enlargement 10; the cover 15, provided with the dome 17; and the sides 16', substantially as described.

In testimony whereof Iaffix my signature inpresence of two witnesses.

CHARLES H. PRESBREY.
